For the sake of elearncss I have 4 a; a segment or bar which is integral with shown the pinion of greater proportionate or attached to the regulator and provided size than is desirable and the number of teeth shown is not the most desirable proportion recommended.

In Fig. 3 I show a modification in which the segment. 4, is made in the form of a loop having teeth, 5, on the inner edge of the loop, the loop surrounding the pinion 6. There is enough transverse spring in the loo to hold the teeth 5' in snug engagement witii pinion 6 and no longitudinal spring to disturb the adjustment. By this means all lost motion or loosencss between segment and inion is avoided.

W mt I desire to claim is l. A watch regulator comprising a worm, a wheel meshing therewith, a lever having a, segment operated by said wheel, said worm being spring )ressed lengthwise.

2. In regu ating mechanism for watches, a toothed segmentaibar rigid with the regulator, a. small inion meshing with said bar, a gear wheel of arger diameter rigid with and concentrie with said inion, a worm shaft, ada ted to be engagetiby the watchmakers too meshing with said gear wheel and a spring tension device engaging said worm shaft, substantially as and for the purpose set forth.

3. In regulating mechanism for watches, a toothed segmental bar rigid with the regulater, a small inion meshing with said her, a 30 gear wheel of arger diameter rigid with and concentric with said pinion, both of said wheels being pivotally mounted on the cock, a worm shaft, ada )tQLl to be engaged by the watchmakers tooi, meshing with said gear :15 wheel and a. spring washer mounted on said shaft, substantially as and for the purpose set forth.

4. A watch regulator comprising a worm, a wheel having V shaped teeth meshin therewith, a lever having a segmental raeii operated by said wheel, said worm being spring pressed lengthwise. I
